To fix an RSAT installation failure on Windows 11, first confirm the PC runs Pro or Enterprise, then identify the exact RSAT capability and install it from an available Windows Update or compatible Features on Demand source. The error code, Windows build, update-source policy, architecture, and language determine which troubleshooting branch applies; the title alone cannot identify the cause.
1. Confirm Windows edition and gather the details that determine the fix
Microsoft’s client installation guidance supports RSAT Features on Demand (FoD) installation on Windows 11 Pro and Enterprise. Home and Standard client editions are not supported for this installation path. Check the edition before trying repairs: an unsupported edition is not an update or component-store problem. See Microsoft’s RSAT installation guidance.
Record the Windows version and build, system architecture, the RSAT tool you need, the exact error text or code, and whether the PC is managed by an organization or offline. Those details matter because update policies can redirect optional component downloads, while a local FoD source must suit the system.

Open PowerShell as an administrator and list the RSAT capabilities available to the running Windows image:

- 1.1 GHz (boost up to 2.4GHz) Intel Celeron N5030 Quad-Core
Get-WindowsCapability -Online | Where-Object Name -like 'RSAT*'Use the exact capability name shown for the tool you need. For example, Microsoft’s documented command for the Active Directory Domain Services and Lightweight Directory Services tools is:
Add-WindowsCapability -Online -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0After the command completes, query that capability again and check its state:

- 256 GB SSD of storage.
- Multitasking is easy with 16GB of RAM
- Equipped with a blazing fast Core i5 2.00 GHz processor.
Get-WindowsCapability -Online -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0Replace the example name with the exact name for your selected tool. Microsoft’s Get-WindowsCapability documentation explains how the command inspects capabilities in a running or offline image and how a source containing capability packages can be used.
3. Choose the installation source that fits the PC
| Installation path | When it fits | What to check |
|---|---|---|
| Online capability installation | The device can obtain the capability from its configured Windows Update or organizational update source. | Use the exact capability name with Add-WindowsCapability; confirm the device can reach the configured source and that policy allows optional component content to come from it. See Microsoft’s RSAT instructions and capability command reference. |
| Local or offline FoD source | Update access is unavailable, or the device is configured to use managed/local content. | Use the applicable Microsoft FoD packages and servicing procedure. Match the source to the Windows release and the device’s architecture and language needs. See Microsoft’s Features on Demand guidance and capability command reference. |
There is a documented platform exception: on Windows 11 version 25H2 Arm64, Microsoft says some RSAT tools are accessed through Control Panel’s Windows Features interface, and RSAT FoDs are not supported in that case. Follow Microsoft’s current FoD guidance for that configuration rather than assuming the usual FoD command path applies.

4. If the failure points to Windows Update or an update policy
An update-related error can indicate that Windows cannot reach its configured source, or that policy sends optional component repair content somewhere else. Check whether the device can contact its assigned Windows Update or organizational update service and whether the applicable policy permits the content source being used. An error code by itself does not establish which cause applies.
For example, a user in a Microsoft Q&A report described error 0x8024402c while installing RSAT on Windows 11 24H2 Enterprise behind a firewall. That is one reported case, not evidence that every occurrence of this code—or every RSAT failure—has the same cause.

5. Use DISM only when there is evidence of broader update corruption
If other Windows Update installations also fail or there is evidence of component corruption, Microsoft documents this elevated command:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
DISM.exe /Online /Cleanup-image /RestorehealthMicrosoft says DISM works best when it can retrieve missing or corrupted files from Microsoft Update. If that connection is unavailable, use a working Windows installation or appropriate repair files available through a network, USB, or DVD as the repair source. See Microsoft’s guidance for fixing Windows Update corruption and installation failures. RestoreHealth is a conditional repair, not a guaranteed fix for an RSAT-specific failure.

6. Be cautious with unofficial local-package workarounds
A March 2026 community reply in a Microsoft Q&A thread about a Windows 11 24H2 FoD source recommended installing CAB packages directly for one reported local-source problem. That community suggestion is not official Microsoft guidance and does not establish a generally supported fix for all 24H2 systems. Prefer documented capability servicing with a compatible source; if that path still fails, retain the exact error and servicing logs for escalation.
